Demi Lovato will let fans into her life when her documentary "Demi Lovato: Stay Strong" premieres March 6 on MTV. Cameras follow Lovato as she tours, goes back to visit the Illinois rehab center where she was treated, and opens up in great detail about her life post-treatment.

While Lovatics got a preview of what's to come from the trailer that dropped a few weeks back, the full picture of Demi's struggles and her life right now will be revealed when the "Stay Strong" airs Tuesday at 10 p.m. ET/PT. Lovato talked to MTV News this week about why she signed on for the doc.

"I was most definitely nervous about opening up to the cameras," she said. "And I was very hesitant to say certain things, but once I was around them for a while, I felt more comfortable and really opened up towards them."

The special goes deep. Demi talks candidly about her issues, from being diagnosed with bipolar disorder to struggling with both cutting and eating disorders. The singer/actress hopes the documentary can help anyone else dealing with similar kinds of pain.

"My goals for my fans? It's to really inspire people," she said. "That's all I hope to accomplish. If there is a young girl at home dealing with the same issues that I'm dealing with, I want to be able to reach out to her and tell her that it's going to be OK.

"You know, I speak about a lot of serious issues and I really hope to get awareness out there about the issues that I dealt with," she continued. "But at the end of the day, I just want people to see what it's like to be in my shoes. I kind of talked about the journey that I've been on and I just want people to take away a positive message. It gets better, you know?"

The special is named after a pair of tattoos Demi has on her wrists that read "Stay Strong." The tats are a tribute to the fans that Lovato said sent her that very message while she was in treatment.
